Mand canine and skeletal maturity /certified fixed orthodontic courses by Indian dental academy

  1. 1. INDIAN DENTAL ACADEMY Leader in continuing dental education
  2. 2. Relationship between mandibular canine calcification stages & skeletal maturity AJO 1993, 104: 262-8 Sandra Coutinho – Guam Peter H. Buschang – Bylor, Dallas Tx Francis Miranda – Bylor, Dallas Tx
  3. 3. • Knowledge of the stage of maturation that a child has attained helps in evaluating his or her progression through expected developmental events. Such information is clinically important in: 1) Helps interdisciplinary health teams assessing patients with various types of short stature, endocrine disorders, and/or metabolic diseases. Its utility is well established in syndrome identification and forensics. 2) A child’s maturity status helps better identify optimal time for certain types of orthopedic treatments. Variations exist between individual children in the ages at which they attain similar developmental events. In addition, there are diseases, systemic disorders and environmental factors that may affect child’s physiologic maturity.

  5. 5. • Relationship between the stages of tooth mineralization of mandibular canine appear to co relate better with ossification stages than the other teeth (studies by Chertkow 1979, 80 and Alicia M. Sierra in 1987) • Interrelationship between skeletal, somatic and sexual maturity have shown to be consistently strong.(Demirjian 1985AJO) • Given the well established relation between skeletal and somatic maturity, stages of calcification of the mandibular canine might be used as a first level diagnostic tool to estimate timing of pubertal growth spurt. • Ease of recognizing dental developmental stages, together with the availability of intra oral or panoramic radiographs in most orthodontic or paediatric practice are practical reasons for attempting to assess a person’s physiologic maturity without resorting to multiple hand wrist radiographs. • The purpose of this study was to verify relationships between canine calcifications and skeletal maturity.
  6. 6. Materials and Methods • Pre treatment dental OPG – 200 boys, 215 girls between 7 – 165 years. • Skeletal age determined from hand wrist radiographs and assessed according to Pyle and Greulich.
  7. 7. • The phalangeal maturity stages and appearance of adductor sesamoid were defined by using the Tanner Whitehouse method.
  8. 8. • The development of the mandibular canines were assessed according to Demirjian stages of dental calification.
  9. 9. Results • Mean skeletal age for the presence of the adductor sesamoid in girls 12.2 years and boys 13.2 years. • The middle phalanx of the third finger shows the highest relationship with canine maturity for both sexes, followed by PP5, DP3. • The PP3 and adductor sesamoid show similar patterns of association with canine maturation.
  10. 10. • Most subjects having attained mandibular canine stage F show no presence of adductor sesamoid. • Stage F – epiphysis of MP3 and MP5 equal to diaphysis. This stage indicates initiation of growth spurt. • Stage G – Eruption of the canine into the oral cavity. Shows adductor sesamoid. Capping of MP3, DP3, PP5. 1 year before PHV in boys. 5 months before PHV in girls. • Stage H – Stage of apical closure. Fusion of epiphysis to diaphysis.
  11. 11. Conclusion • Close association exists between mandibular canine calcification stages and skeletal maturity indicators. • The intermediate stage between stages F and G should be used to identify early stages of pubertal growth spurt. • While there is a close relationship between canine calcification and skeletal maturation, canine calcification cannot and should not be used as a sole criterion to predict developmental landmarks (I.e., onset of puberty, PHV etc.) • Dental calcification stages of mandibular canine are readily available and easily recognized indicators of maturity status of a person. They are simple, first level diagnostic test to determine whether additional, more sensitive measures of maturity are needed.
